Study finds unique form of chronic sinusitis in older patientsJan. 18, 2019, 9:15 AM
Older patients with a diagnosis of chronic sinusitis — a disease of the nasal cavity and paranasal sinuses that often persists over many years — have a unique inflammatory signature that may render them less responsive to steroid treatment, according to a new study published by Vanderbilt researchers.
The study published in the Journal of Allergy and Clinical Immunology examined tissue and mucus specimens of 147 patients between the ages of 18 to 78 who required sinus surgery for their chronic sinusitis.
With an initial goal of identifying subgroups of patients based on their inflammatory signature — the different cytokines and inflammatory proteins found in tissue or mucus — Vanderbilt investigators recognized that one of the identified subgroups was enriched in patients over age 60.
Intrigued by the findings, the team compared all patients according to age by examining their histopathology, tissue specimens taken during surgery, and the immune markers and inflammatory proteins found in their tissue and mucus, and noticed they were strikingly different.
